Detective Sergeant Rick Hunter (Fred Dryer) is a good cop, who has a few things going against him. One is the fact that he, albeit unintentionally, injures his partners, which that not too many cops want to be his partner. Another is that his Captain has it in for him, and the fact that some of the people in his family are mobsters. Hunter teams up with Detective Sergeant Dee Dee McCall (Stepfanie Kramer), another cop who the other cops don't like. But nevertheless, they prove to be quite a formidable duo. As stated, Hunter's Captains during the first season had it in for him, but during the second season, Hunter's new Captain, Wyler (Bruce Davison), did not have a grudge against him, but liked to do things by the book, which Hunter sometimes didn't do. During the third season, his new Captain, Charles Devane (Charles Hallahan) got along well with Hunter and McCall. After six seasons, Stepfanie Kramer left the show. During the seventh season, Hunter and Devane were transfered to the Metro Division and were joined by Joanne Molenski (Darlanne Fluegel). Eventually, Molenski left and was replaced by Sergeant Chris Novak (Lauren Lane).
